<Prior art> As shown in Fig. 4, a conventional belt conveyor roller has a structure in which bearings (b) are arranged at both ends of a cylindrical body (a) having a length corresponding to the belt width. (
Since the area around b) is a space (e), if the seal td) provided on the end face is defective or worn out, moisture or dust may enter the space (e), easily causing damage. corrosion,
There were three cases of damage or rotational failure. Furthermore, since this cylindrical body (a) usually uses a steel pipe, it is heavy if it is long, making it difficult to attach and detach.

An example of this type of roller structure is the Japanese Patent Publication No. 54-130
There is a method such as that shown in Publication No. 71, which has the effect of reducing the weight, but since the purpose of this invention is to deform following the curved belt shape, the bearing Since the bearing is covered from both sides by the housing, the protection from moisture and dust mentioned above is not as complete as described above, and the number of parts per bearing is large, so the weight is still large. The drawback is that the manufacturing process for each roller is complicated and maintenance is poor.

Furthermore, there is a receiving device shown in Japanese Utility Model Publication No. 54-25814 that has a structure in which a plurality of short individual rollers are arranged, but even with this receiving device, the bearings at both ends cannot be protected. Since it uses a normal housing, it has the same drawbacks as above.

<Means for Solving the Problems> In the present invention, a cover made of resin such as rubber or urethane is used instead of the conventional housing to protect the bearings, which are components of belt conveyor rollers, from dust and water. , and by fixing the roller body directly to the roller shaft, the overall structure is simplified.The gist is that the outer peripheral surface and both sides of the bearing are covered with a resin material such as rubber or urethane. This is a belt conveyor roller characterized in that a cover is attached and a plurality of roller bodies are inserted and fixed to a roll shaft at required intervals.

The structure of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, a roller body (A) is inserted and fixed to a roller shaft (B) at required intervals, Various methods can be considered for fixing the (in), such as interposing a thin sleeve between the inner wall surface of the bearing and the outer circumferential surface of the roller shaft, using adhesive, or using pins.

In order to actually manufacture this roller body (A), a preheated bearing is placed in a mold of the desired shape (not shown).
A method is adopted in which resin raw materials consisting of a base resin and an effect agent are injected in a mixed state, and then heated and cured. At this time, tape is placed on the inner race and grease stopper ring on the side of the bearing (1). Attach the tape to prevent resin from flowing into the bearing from between the inner race of the bearing and the grease stopper ring, and apply a release agent to the top surface of the tape to prevent the resin from seizing.
